1) Obtain another Actiontec. Set it up as the primary router, which will handle WAN connectivity to the ONT via coax.
The OP's issue is with the Actiontec as primary. Why would he want to obtain a second Actiontec, just to use that as primary? He wants his DD-WRT router as primary.
I previously pointed the OP to the trade-offs FAQ, although I didn't specifically point him to option #4 or #5 which would use his existing Actiontec as a MOCA bridge and allow the DD-WRT to be primary.--
